Title: Improvements in apparatus for cleaning metal parts and other articles
IPC: C23G5/04
Filed: 1946-10-03
Abstract: <PICT:0617478/III/1> The apparatus for cleaning articles by spraying them with paraffin or other liquid according to the parent Specification is modified by embodying therein a device for separating atomized cleaning liquid from the air escaping from the spraying nozzle or from the air vent pipe of the subsidiary tank. This device comprises a casing with an inlet for the air to be treated, a pad of absorbent material, such as felt, against which the air is caused to impinge, a spring-controlled drain valve for the separated liquid and an outlet for the cleaned air.  In Fig. 1, the spraying nozzle 15 of the cleaning apparatus is inserted into inlet 16 of a cylindrical casing 1.  This casing is provided with pad 4 of absorbent material, spring-controlled drain valve 6 and air outlet pipe 19.  Valve 6 is normally open, but closes under the pressure of the air entering casing 1.  The outlet 18 on pipe 19 is enclosed by perforated cap 21 and a baffle plate 22 is centrally supported on arms 23.  This baffle plate is of smaller diameter than the outlet so as to leave an annulus through which the air current has to pass. Casing 1 may be formed as a separate compartment of the main tank of the parent Specification.

Title: Spinnerets
IPC: D01D5/32
Filed: 1965-07-12
Abstract: 1,055,756. Spinnerets. E. I. DU PONT DE NEMOURS & CO. July 12, 1965 [July 13, 1964], No. 29456/65. Heading B5B. In a spinneret assembly comprising a filter block, spinneret plate and means for attaching the assembly to a spinning machine, the filter block has two separate filter cavities and two symmetrical polymer distribution channels each connected to a filter cavity by a series of tunnels, each distribution channel defining a path extending in opposite directions, from its connected filter cavity, towards the periphery of the filter block, circling towards the interior of the block, and terminating in opposed straight end portions having a tapered depth which is a minimum at the extreme ends. The straight end portions of both distribution channels are parallel to each other and to a row of orifices in the spinning plate to which they are connected. The assembly may be used for spinning conjugate or homogeneous filaments. The assembly 10 (Fig. 1, not shown) comprises a top plate 12, filter block 14 and spinneret plate 16 held in position against a spinning machine (not shown) by ring 200. When spinning conjugate filaments, polymer A enters port 26 and flows via filter cavity 28 and series of tunnels 30, 32, 34, 36, 38 to distribution channel 40. Polymer B enters port 42, and reaches distribution channel 56 via filter cavity 44. Channel 56 defines a path in the filter block which extends towards the periphery of the block, circles round at 58, 60 and terminates in straight portions 62, 64 (Fig. 22. not shown). Channel 40 defines a similar path ending in straight portions 66, 68. The width of channels 40, 56 is constant but the depth decreases in straight portions 62, 64, 66, 68, being a minimum at the extreme ends. Polymer A is then forced through capillary 70, and mingles in orifice 74 with polymer B, which is forced through capillary 72. A series of orifices is located in line with orifice 74. If quenching air flows from direction 75, the filaments are uniformly quenched. The capillaries 70, 72 and orifices 74 are formed in removable insert 76. When homogeneous filaments are required, insert 76 is replaced by one in which the capillaries, e.g. 70, lead directly to the orifices, e.g. 74. so that each filament is formed completely from one polymer supply. Insert 76 may be modified to produce sheath-core filaments (Specification 1,017,639).- A plurality of pins, 78, 80 inserted in holding ring 20, engage groove 82 located in spinneret plate 16 (Fig. 3, not shown) and the assembly attached by engaging the holding ring into threads on the spinning machine. Ramp 86 and cut-out 84 on the spinneret plate enable rapid removal and replacement of the spinneret assembly.

Abstract: 509,733. Coiling. HOFMANN & CO., A. Oct. 12, 1938, No. 29570. Convention date, Oct. 15, 1937. [Class 83 (iv)] Lamp filaments are made from a continuous wire by clamping the end of the wire to a mandrel, rotating the mandrel to effect coiling, forming a straight leg on the coil, severing and stripping the coil from the mandrel. The mandrel A is carried on a wire gripper C rotated through a clutch g<6> from an electromotor. A cam shaft beneath the mandrel is driven through gearing 41 and carries cams for actuating the elements of the machine. The gripper C is actuated by axial movement of a rod C<5> by a cam actuated lever C'. The clutch is operated by a member M which is locked against movement until a spring is stressed and it is then released to effect quick operation of the clutch and to insert a locking dog j to stop the mandrel in a predetermined position. A wire guide B receives-wire from a spool and guides it along the mandrel. The guide is mounted on a support N moved transversely to the mandrel on a carrier P which has an arcuate movement effected by cranks from the cam shaft. The carrier P is mounted on a carriage Q moved axially of the mandrel. Pivoted shears E shear the wire and a stripper is raised and swung by cams to strip and remove the completed coil. Operation. The wire guide B moves to insert the end of the wire into the gripper C which is then closed by the lever C<8>. The clutch g‹ is then operated to rotate the mandrel and effect coiling. The wire guide B is moved by the carriage Q to determine the pitch of the helix. The end of the mandrel is supported by a rest D which moves with the guide. At the end of the coiling the mandrel is stopped in a position determined by a stop and the guide B is reracted by movement of the support N over the wire to form a double leg on the end of the helix The guide is then swung about 90 degrees by the arcuate movement of the carrier P to bend the leg of the wire, about the mandrel rest D, into alignment with the helix. The shear E is then actuated to sever the leg midway between its ends. The mandrel rest is then lowered and the guide retracted. The stripper is swung to a position beneath the coil and is raised and retracted to strip the coil from the mandrel when the gripper is opened.

Title: Preparation of spirit duplicating masters
Inventor: HOOF ALBERT EMIEL VAN
IPC: B41M5/04
Filed: 1962-07-30
Abstract: 1,064,814. Photographic transfer processes. GEVAERT PHOTO-PRODUCTEN N. V. Sept. 26, 1963 [July 30, 1962], No.29837/63. Addition to 981,508. Heading G2C. A method for producing a printing master suitable for use in spirit duplicating comprises imagewise exposing a gelatine silver halide emulsion and treating the exposed layer with a tanning developer and a softening agent for gelatine so that the layer is tanned in the exposed areas and softened in the unexposed areas, pressing the wetted exposed layer into contact with a dyeformer layer so that the softened gelatine areas are transferred to the dye-former layer on peeling the layers apart, and subsequently converting the dye-former which is present in either the areas to which the gelatine was transferred or the remaining uncovered areas and/or the dyeformer which has been transferred to the tanned areas of the emulsion, to a spirit-duplicating dyestuff. Specified dye-formers are diazonium salts and leuco bases of triaryl-methane dyes. In the examples, a direct positive gelatine silver halide emulsion is imagewise exposed and developed in a tanning developer solution containing urea as softening agent. The developed layer is pressed against a layer containing leuco malachite green and then stripped apart discarding the dye-former layer with the transferred areas of softened gelatine. The emulsion, which bears dye-former transferred thereto in the tanned areas, is treated with acidic potassium permanganate to produce a spirit duplicating matrix. Alternatively, a negative silver halide emulsion containing urea and a tanning developer is imagewise exposed and treated with alkali to produce a tanned and developed emulsion. The developed emulsion is pressed into contact with a dye-former layer and pulled apart to leave a dye-former layer with the softened areas of gelatine adhering thereto. This layer is then treated with an oxidant to produce a dye image and a spirit-duplicating master. Alternatively, the layer may be contacted with a receptor sheet and the gelatine plus the dye-former under the gelatine is transferred to the receptor sheet which is then developed and used as a spiritduplicating master. No development of the dyeformer may be required if the oxidant is added to the spirit duplicating liquid or to the copy sheet.
